PRKAA1

Across TCGA pan-cancer cohorts, PRKAA1 mass-spec protein differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of PRKAA1’s most consistent transcriptional readouts.

The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where PRKAA1 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types PRKAA1 is over-expressed in tumor, although a few such as LSCC and COAD show the opposite, repressed pattern.

PDAC, LSCC, and CCRCC are the cancer types where PRKAA1 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in PRKAA1 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
